00:01 I have an angle, and i'm going to call it theta, and that's equal to negative 3 pi over 5.
00:08 So if i draw that angle in standard position, vertex at the origin, an initial side on the positive x -axis, a negative angle just means a rotation clockwise.
00:22 So i'm going to rotate negative 3 pi over 5, and a reference angle is formed by, the terminal side of an angle theta and the x -axis...
